Familiarity: I've put it through the wringer
This mug has a great design... it just don't spill when locked or unlocked if you knock it over. Purpose of the lock is so it doesn't leak or spill if the button gets pushed accidentally...ie. in your pack. When lock, no chance. It is all in the design of the lid which is easy to use. My previous mugs have been flip tops of some kind so not having to open a lid is very nice. The only little issue is cleaning the lid., you just can't get in there and wipe it down unless you use a Qtip. For quick cleans hot water, put lid on and shake like your making a martini. Deep clean the DW will do the job. Keeps your coffee or in my case espresso hot for hours. I use it daily and have taken it on all kinds of trips...no issue what so ever. I bring my portable espresso maker wherever I travel so I have used it everyday no matter where I am. Your just a push of a button away from your fix... enjoy!
